Commissioning expected date
The coal-based blast furnaces will be replaced by hydrogen-powered direct reduction plants. The iron produced there, which will have been directly reduced with hydrogen, will be liquefied for the first time in downstream, specially developed melting units to produce high-quality hot iron. All subsequent production steps can take place in the existing plant structure, including the steel mills, thus enabling an efficient transformation.

Commissioning expected date
As part of its tkH2Steel® transformation project, thyssenkrupp Steel has developed an innovative and technologically leading concept for decarbonizing steel production. The coal-based blast furnaces will be replaced by hydrogen-powered direct reduction plants.The iron produced there, which will have been directly reduced with hydrogen, will be liquefied for the first time in downstream, specially developed melting units to produce high-quality hot iron. All subsequent production steps can take place in the existing plant structure, including the steel mills, thus enabling an efficient transformation. In the new plant concept, the entire premium product portfolio can thus be produced with low CO2 emissions without compromising on quality. tkH2Steel® thus represents an efficient and exemplary path towards climate-friendly steel production.
